How to remove and install Coolant Reservoir?

Drain the cooling system. If the coolant is relatively new and still in good condition, it can be saved and reused. Note: On four-cylinder engine models, there is an additional drain plug on the bottom of the water pump. Be careful to clean up any spilled coolant as stated in the Warning at the beginning. Disconnect the coolant reservoir hoses by sliding the hose clamp away with pliers and then removing the hose from the reservoir fitting. Remove the coolant reservoir mounting fasteners. Clean out the reservoir with soapy water and a brush to remove any deposits inside. Inspect the reservoir carefully for cracks. If you find a crack, replace the reservoir. Installation is the reverse of removal. Refill the cooling system with the proper concentration of antifreeze.
